Team Circle Image Slider With Lightbox < 1.0.1 - Image Data Update via CSRF

Description

The plugin is vulnerable to Cross-Site Request Forgery due to missing or incorrect nonce validation on the circle_thumbnail_slider_with_lightbox_image_management_func() function. This makes it possible for unauthenticated attackers to edit image data which can be used to inject malicious JavaScript, along with deleting images, and uploading malicious files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
